The SMSS (Squad Mission Support System), also known as the "Ox", was initially developed as a Lockheed Martin initiative to lighten the load for light infantry Soldiers and Marines. A highly mobile 6x6 unmanned vehicle, the SMSS can carry 1,200 pounds of gear for a 9- to 13-person squad, and it can accompany the squad on many missions through heavy terrain.
